  • Patent number: 11215903
    Abstract: Soft box mount, including a receiver block for receiving an expander strut of a soft box. The receiver block includes, in this order, an inward part, a transverse pivot axis, and an outward part, the outward part of the receiver block being configured to receive a proximal end of the expander strut; and a bar block which is configured to be movable between a first, non-use position, in which the inward part of the receiver block may intrude into a recessed part of the bar block, and a second, use position, in which a non-recessed part of the bar block urges, from a light source side, the inward part of the receiver block to assume a position radially inward of the pivot axis of the receiver block, thereby urging the outward part of the receiver block to assume a position radially outward of the pivot axis of the receiver block.

  • Publication number: 20200217840
    Abstract: A field apparatus (also referred to as a “biosampler”) is configured to automatically capture multiple samples of an aqueous medium (for example, water from a lake) and process same to preserve unstable analytes in the field. In this way, a set of samples from the aqueous medium can, for example, be captured at multiple points in time, processed with a biopreservative to preserve unstable analytes (for example, RNA) and then later collected for further analysis. Alternatively, multiple samples of the aqueous medium can be collected and preserved at one moment.

  • Patent number: 10555224
    Abstract: Example embodiments presented herein are directed towards a stateless mobility management node, and corresponding methods therein, for handling a mobility procedure for a wireless device within a wireless communications network. The example embodiments provide for the management of a common external database shared by the stateless mobility management node and at least one other stateless mobility management node, and storing context information for wireless devices served by the stateless mobility management nodes. Such management allows for migrating the network towards a virtualized and stateless architecture. Thus, stateless mobility management nodes with an external database may interoperate with legacy stateful mobility management nodes.

  • Patent number: 10368220
    Abstract: A server for controlling user MTC devices. The server ascertains if a user MTC device has an IP connection to a cellular access network, and if so, sends a message to trigger the user MTC device to initiate an application defined in the message. If a user MTC device does not have an IP connection, the server ascertains if the user MTC device is a mobile or a stationary user MTC device, and for a stationary user MTC device, the server sends a message to the cellular access network to trigger the user MTC device to initiate an IP connection, and for a mobile user MTC device, waits until the user MTC device has an IP connection, and for both kinds of user MTC devices, when the user MTC device has an IP connection, transmits a message to the user MTC device to initiate an application defined in the message.

  • Patent number: 10362451
    Abstract: A method, device, and computer program product for facilitating device-to-device, D2D, communication among wireless communication devices, WCDs, is provided. The device is a first WCD that receives a wireless packet broadcasted by a second WCD. The wireless packet has one or more of i) a group identifier that identifies a group to which the second WCD belongs and ii) an application identifier that identifies an application which generated at least part of the wireless packet. The first WCD extracts from the wireless packet one or more of the group identifier and the application identifier. The first WCD determines whether to discard the wireless packet based on the one or more of the group identifier and the application identifier extracted from the wireless packet.
